A roll whose bend can be controlled has support elements which are designed as ring elements with an annular pocket and an annular pressure surface. The interior space enclosed by the ring element is connected to an outlet line having an adjustable throttle element. By appropriately adjusting the throttle element, any arbitrary intermediate pressure can be maintained in the interior space. Therefore, a wide adjustment rage for the support force is possible, and needs only a feed line for the pressure medium and an outlet line. In this way, relatively large and relatively small path loads can be processed in the roll gap without a major structural change.
